1851 dnl This macro searches for a GNU version of make. If a match is found, the
1852 dnl makefile variable `ifGNUmake' is set to the empty string, otherwise it is
1853 dnl set to "#". This is useful for including a special features in a Makefile,
1854 dnl which cannot be handled by other versions of make. The variable
1855 dnl _cv_gnu_make_command is set to the command to invoke GNU make if it exists,
1856 dnl the empty string otherwise.
1858 dnl Here is an example of its use:
1860 dnl Makefile.in might contain:
1862 dnl # A failsafe way of putting a dependency rule into a makefile
1864 dnl $(CC) -MM $(srcdir)/*.c > $(DEPEND)
1866 dnl @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
1867 dnl @ifGNUmake@ include $(DEPEND)
1868 dnl @ifGNUmake@ endif
1870 dnl Then configure.in would normally contain:
1872 dnl CHECK_GNU_MAKE()
1873 dnl AC_OUTPUT(Makefile)
1875 dnl Then perhaps to cause gnu make to override any other make, we could do
1876 dnl something like this (note that GNU make always looks for GNUmakefile first):
1878 dnl if ! test x$_cv_gnu_make_command = x ; then
1879 dnl mv Makefile GNUmakefile
1880 dnl echo .DEFAULT: > Makefile ;

1884 dnl Then, if any (well almost any) other make is called, and GNU make also
1885 dnl exists, then the other make wraps the GNU make.
